SPARK-ARRESTER AND SMOKE-CONSUMER.

SPECIFICATION forming part of Letters Patent No. 326,671, dated September 22, 1885,

Application filed Juno 6, 1885.

To all whom, it may concern.-

Be it known that we, JOHN G. NEssEL and YVILLIAM H. STEINBREOHER, citizens of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in a Combined Spark-Arrester and Sn1oke-- Consumer; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our present invention relates to a combined spark-arrester and smoke-consumer, which we have illustrated in connection with a boiler of a locomotive; and our invention consists in the arrangement of parts, as hereinafter set forth, and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a longitudinal elevation in section. Fig. 2 is an end elevation in cross section on dotted line 1 1 of Fig. 1. Fig. 3

is an end elevation in cross-section on dotted line 2 2 of Fig. 1. Fig. etis a detail, as hereinafter set forth.

B is the boiler; F, the flues; g, the gratebars; A, the ash-pan, and S the smoke-stack, all of which are common. lVe bolt or rivet to the fluehead D of the boiler a conical hood, H, having a central opening. Around said opening we rivet a horizontally-projecting discharge-tube, E. Fitting over said tube is an extension tube or cylinder, 0, which is moved horizontally over the inner tube for the purposes hereinafter set forth. Between the heads D and n of the boiler we locate a central head, R, having a central dischargeopening, 1.. Said opening is adapted to receive the free end of the extension-cy1inder O. Said head is also provided with two upper openings in which we secure the funnelshaped fines a a. Said fines are arranged on opposite sides of the boiler, passing through the conical head H, entering two of the top lines of the boiler. (See Figs. 1 and 2.) The central head has also an opening at the bottom, in which we secure a discharge-pipe, Z.

(No model.)

and when the door is closed, as in Fig. 1, said spreader stands directly in front of the discharge-opening t of the central head.

0 is a steam-pipe, which leads from the cylinder or cylinders of an engine. Through said pipe the exhauststeam is conveyed. Said pipe passes upward through the hood H. Its upper end is bent over horizontally at c, and said bent-over portion stands directly in the center of the opening in the conical head H, its open end facing the opening leading into the discharge-tube E, as clearly shown in Fig. 1.

The operations are as follows: The fire for raising the steam is built upon the grate-bars g in the usual way. The sliding tube 0 is drawn back, as shown in Fig. 1, by means of a lever and rod (not shown,) extending back to the cab, when the draft will be through the flues of the boiler (excepting the upper flues connecting with the flues a a) out through the tube E, and upward through the smokestack. As soon as steam is up and the engine is started, the sliding tube 0 is forced horizontally until its open end enters the port hole t of the central head, when the exhauststeam from the cylinder of the engine will be driven through the tubes or discharge-cylinders E O,increasing the draft through the flues, forcing the smoke and cinders against the spreader h, when the current will be divided, the lighter particles passing upward, as indicated by the arrow, returning through the fines a a, coupled with the upper flues of the boiler, the heavier smoke and cinders,passing downward from the spreader h, as indicated by the arrow, being forced by the jet of steam through the pipe Z into the conveying-pipe D back into the ash-pan below the grate-bars, when it passes up through the flames, being consu'mech- Should cindcrs fallonto the bot tom of the chamber T while. the .tube 0. is drawn back with the engine idle, the starting of the engine with the tube 0 extended, as specified,the eXhaust-steam,passing through the small pipe Z into themouth z of the conveying-pipe D, will cause a suction at the mouth 1, when said cinders will be drawn into the pipe D and blown into the ash-pan.

Having thus fully set forth our present invention, what we claim as new, and desire to secure by Letters patent, is-

1. In a combined spark-arrester and smokeconsumer, the combination,with a conical hood attached to the flue-head of a boiler, said hood supporting a horizontally-projecting flue or tube over its central opening, said tube sup- V porting a sliding tube, of a central head, B,

located between the heads D and it, said central headsupporting fiues a a, as set forth, and

dischargepipe Z, leading into the mouth of into the conical hood having a horizontal dis- V charge, as and for the purposes set forth.

2. In a combined spark-arrester and smokeconsumer, the combination, with a boiler and its lines, and the conical hood,attached as specified, said hoo'd having a central discharge with tubes E0 mounted thereon, as set forth, of an exhaust-pipe leading from the cylinder of an engine into said hood, said exhaust-pipe having a horizontal discharge at right angles to and .below the smoke.- stack, a central head, its induct-port t and discharge-ports specified, and a V- shaped spreader located on a horizontal line with and infront of the port t of the central head, as and for the purposes specified. 3. The combination, with the boiler-head D and the conical hood attached thereto,having a central opening, said hood supporting the discharge-tubes E O, as specified, of an exhaust; pipe leading from the cylinderv of an engine into said hood, having the curvedend portion a, said hood and discharge-tubes located in the chamber T below the smoke-stack, substantially as specified.

In testimony whereof we affiX my signatures in presence of two witnesses.
